Description

[Detailed Description of the Invention] This invention relates to a watertight structure between a hinge side stile of a shoji and a window frame in an outward folding window, a projecting window, a casement window, etc.

The watertight structure on the hinge side of the shoji of the proposed outward-folding window uses the isobaric principle to ensure effective watertightness, and the hinge part is configured to be easily processed and repaired. The details of the present invention will be explained with reference to the drawings implemented on the window.

In FIG. 1, a horizontal bar 5 is inserted into the upper part of a window frame consisting of upper and lower horizontal frames 1 and 2 and left and right vertical frames 3 and 4, and a lower frame 2 and left and right vertical frames 3 with the horizontal frame 5 as the upper frame. , 4 is fitted with a glass 6, and a sliding shoji 7 is fitted into a frame formed of an upper frame 1 with the horizontal beam 5 as a lower frame, and left and right vertical frames 3 and 4.

The above-mentioned outward-tiling shoji 7 has a glass 12 fitted in a frame consisting of upper and lower horizontal frames 8 and 9 and left and right vertical frames 10 and 11, and is shown in the second figure from the lower side of the lower side of the lower horizontal frame 9. As shown in the figure, a front wall 13 extending over the entire length of the lower stile projects downward, and a socket portion 14 of a hinge having a C-shaped cross section is formed at the projecting end.

On the other hand, the upper surface of the horizontal bar 5, which is the lower horizontal frame of the outward folding window, is formed in the shape of a single high step toward the indoor side, as shown in the second figure, and the entire length of the horizontal bar 5 from the indoor end of the upper surface is formed. The rear wall 15 extends upward, and a tight material fitting groove 16 is formed at the projecting end, and a tight material 17 made of an elastic material such as rubber or synthetic resin is inserted into the fitting groove.
The support plate 18 of the hinge is fitted on the upper surface of the horizontal beam 5 with screws 1.
9,... is fixed almost horizontally toward the outdoor side. The support plate 18 is a plate-shaped body extending the entire length of the horizontal beam 5, and has a shaft 20 at its outdoor end and an outside air introduction hole 21 in the middle. The socket part 14 of the shoji 7 is fitted to support the shoji 7 so that it can be opened and closed freely.
When it is closed as shown in FIG. An equal pressure horizontal space A communicating with the outside air through the outside air introduction hole 21 is formed between them.

With the above structure, outside air enters the horizontal space A through the outside air introduction hole 21 and maintains the horizontal space A at the same pressure as the outside pressure, thereby improving the watertightness of the tight material 17 portion based on the equal pressure principle. This will ensure that.

In addition, shoji is generally fitted into a window frame fixed to the frame from the outside of the room, but in this case, the support plate 18 is separate from the window frame and is fixed with screws, so the above-mentioned fitting of the shoji is not possible. In this case, if the shaft part 20 of the support plate 18 is inserted from the side into the socket part 14 of the shoji 7 and the support plate is attached to the shoji in advance, the shoji 7 can be fitted into the window frame and the support plate 18
By fixing the shoji to the window frame with screws 19, the sliding shoji can be easily installed.

If this proposal is to be applied to a projecting window, a casement window, etc., the design may be changed as appropriate according to the above example. Further, in each of the above examples, the tight material 17 may be attached to the shoji side.

According to the watertight structure on the hinge side of the shoji in the outward-folding window of this invention, when the shoji is closed, an equal pressure space is formed between the shoji and the frame that communicates with the outside air through the outside air introduction hole, so the equal pressure principle of the space is established. Based on this, it is possible to ensure sufficient watertightness of tight material parts and other joint parts, and the base plate can be attached and detached with screws, so this is recommended when drilling outside air introduction holes in the base plate. Not only does it have the advantage of being easy to process as it can be done separately from the frame, but it can also be replaced with a new support plate if the shoji connecting part etc. is damaged, making it extremely effective in practice.

Claims (1)

[Scope of Claim for Utility Model Registration] In a window frame, a tight material is interposed between the indoor side of the frame and the shoji, and a support plate having outside air introduction holes is screwed to the outdoor side of the frame, and the support plate A shoji is rotatably connected and supported at one end of the shoji, and when the shoji is closed, the shoji comes into pressure contact with the indoor side of the frame via a tight material, allowing the outside air to flow between the shoji, the support plate, and the frame. A watertight structure on the hinge side of a shoji screen in an outward-folding window, etc., which forms an equal pressure space that communicates with the outside air through an introduction hole.
